The Trump administration will push for a broad reset of "outdated tariff determinations" at the World Trade Organization to right what it sees as years of unfair treatment of the United States, a top trade official will tell lawmakers on Wednesday.
US Trade Representative Robert Lighthizer said changes in the tariffs set by the Geneva-based WTO were urgently needed to better reflect current economic realities.
"Many countries with large and developed economies maintain very high bound tariff rates, far above those levied by the United States," he said in prepared testimony for separate hearings to be held by the US House of Representatives Ways and Means Committee and the Senate Finance Committee.
He said Washington would also seek broader support for its proposals concerning notification enforcement and "special and differential treatment" for developing countries.
The Trump administration has railed for years about the WTO's failure to hold China accountable for unfair trade practices, and insists that China - the world's second largest economy - should no longer be treated as a developing country.
Lighthizer said the WTO and its Appellate Body had treated the United States as "the world's greatest trade abuser" despite its large trade deficit, by finding the United States at fault in up to 90 percent of disputes filed before the trade organization.
Doing so had undermined the WTO's negotiating process since countries now believed they could obtain better outcomes through litigation, he said.
Washington last year already crippled the WTO's ability to intervene in trade wars after blocking appointments to the Appellate Body, which rules on appeals in disputes.
Lighthizer said the Trump administration also would continue to pursue formal challenges to practices of foreign countries that it believes violate WTO rules, such as the US probe of digital services taxes announced on June 2.
He said the administration was also considering lowering the current $800 "de minimus threshold" up to which products can be shipped into the United States duty-free. The US rate far exceeds that of its major trading partners, Lighthizer said.
